rish sea moss is a viral supplement today, used in numerous industries and acclaimed positively by healthcare professionals. There’s nothing miraculous about it, though.

By being abundant in antioxidants, vitamins, minerals, enzymes, amino and fatty acids, fiber, proteins, and more, Irish sea moss can significantly impact your health if you let it into your nutrition.

In this article we are going to explore the key Irish sea moss nutrition facts, find out how many nutrients does sea moss have, and explain how you benefit from eating sea moss — all from the scientific point of view.

What nutrients are in sea moss?

Now, what does sea moss contain? In the face of myriads of articles claiming that sea moss contains from circa 90 to circa 120 pivotal nutrients, the real quantity of ingredients in sea moss is not entirely estimated.

Still, the nutritional content of Irish sea moss is beyond impressive. According to the U.S. Department Of Agriculture(1), two tablespoons of Irish sea moss (Chondrus crispus) contain the following nutrients:

  • Antioxidants and vitamins — sea moss nutrients include vitamins crucial for your immunity. A, E, C, beta-carotene, and potassium go to your body with a tablespoon of Irish sea moss gel.
  • Minerals — sea moss contains phosphorus, iodine, potassium, calcium, chloride, magnesium, sodium, and sulfur — all crucial for maintaining various physiological functions like bone health, regulating blood pressure, supporting muscle and nerve function, and facilitating multiple metabolic processes.
  • Amino acids — Irish moss is dense with essential and nonessential acids like tryptophan, GABA, glycine, alanine, arginine, proline, glutamic, aspartic acids, methionine, and tyrosine.
  • Fatty acids — While sea moss may not be exceptionally rich in omega fatty acids, it still contains these essential compounds, which play a vital role in adequately functioning your cells, particularly those in your brain and eyes.

Regularly incorporating these nutrients, in conjunction with a well-balanced diet, can do wonders for your body! By the way, you have a chance to learn about the evidence-based effects of Irish sea moss by reading our Case Studies and visiting our YouTube channel!

How can Irish moss benefit your health?

Imagine what all the above-described vitamins and minerals can give your health. However, as with all supplements, the desired result can only be achieved in the long run. This way, if you stay consistent with Irish sea moss, you may start seeing the following changes in a few weeks:

Reinforced immunity

The immune system benefits a lot from the antioxidants Irish sea moss is packed with. The response of your immunity(2) is enhanced and your body fights off viruses and pathogens effectively. The vitamins A, E, and C also impact your gut’s digestion, which decreases the risk of related diseases.

health benefits of eating sea moss

Enhanced digestion

Being a wonderful source of fiber, sea moss is a natural food for your gut bacteria. The prebiotics in your guts grow in amount and have a positive impact on your microbiome(3).

Improved digestion also affects your metabolism and may benefit your weight loss efforts. Finally, since Irish sea moss nutrients contain fatty acids, the supplement may also help you cushion inflammation-related conditions such as acid reflux, gastritis, and ulcers(4).

Stronger heart and arteries

Though sea moss doesn’t contain collagen, it effectively boosts the natural production of it in your body. Reduced overtime collagen can lead your arteries to exhaust, which affects your heart. By promoting collagen, the marine superfood helps consolidate your arteries(5), muscles, and joints.

Mind clarity and energy

Some research shows that contained in sea moss fatty acids, amino acids, and minerals like Iron and Magnesium help your brain keep fit — especially if you often run yourself down or live in a stressful environment. The above-described nutrients of sea moss remove brain fog, make you more emotionally stable, increase your energy levels, and help you stay focused throughout the day.

Improved skin, nails, and hair

Omega fatty acids along with vitamins A, E, and C can help you achieve the dream of bright and strong hair. What’s more the collagen-boosting property of the seaweed might significantly consolidate your nails and promote skin cell turnover. Sea moss also aids with acne treatment and can benefit your skin a lot by controlling its production of sebum — a natural skin oil.

Before incorporating sea moss for inflammation treatment, consult with your healthcare provider first!

Does Irish moss cause side effects?

The safe dose of sea moss is two tablespoons distributed throughout the day. We don’t recommend using more than two tablespoons. The best way to start using sea moss is by starting with one tablespoon a day.

To avoid overusing iodine and enjoy the benefits without the discomfort in your guts, don’t exceed the recommended dose, and take your sea moss supplements during or after your meals!

To sum up

Irish sea moss, also known as Chondrus crispus, is a highly beneficial supplement. Irish sea moss facts are beyond impressive. It is organic, and vegan-friendly, and it is dense in nutrients such as antioxidants, minerals, vitamins, fatty and amino acids, enzymes, and fiber.

The regular use of Irish sea moss helps you support your immunity, better digestion and metabolism, lower blood sugar and cholesterol, consolidate your heart, guts, arteries, bones, nails, and joints, and improve energy levels and skin state. 

As with any supplements, the valuable seaweed can cause nausea, diarrhea, and other side effects if you overdose on the recommended serving.
